Factors Affecting Carboxyl End Groups in Textile-Grade Polyester Chips
An important influencing factor in textile-grade polyester chips is the carboxyl end group (-COOH). These groups form mainly during the esterification and polycondensation stages. Incomplete esterification reactions can leave carboxyl groups in the final product. Side reactions such as thermal degradation, thermo-oxidative degradation, and etherification in the polycondensation reaction will also produce carboxyl end groups.
How do we control the carboxyl end group?
1. Change esterification conditions
The conditions in the esterification tank, including the molar ratio of EG to PTA, esterification temperature, esterification degree, and esterification pressure, directly affect the CEG content in polyester chips. Here are four factors to consider:
1.1 EG/PTA molar ratio
When the molar ratio increases (i.e. the PTA ratio decreases), the carboxyl content decreases. This will lead to a decrease in -COOH content in polyester chips. Conversely, lower molar ratios increase â??COOH content.
1.2 Degree of esterification
About 95% of the esterification occurs in the esterification tank. As the liquid level increases, the material remains in the tank longer. This results in more complete esterification and lower -COOH content. Conversely, lower levels increase -COOH content.
1.3 Esterification temperature
Esterification reaction is an endothermic reaction. Higher temperatures push the reaction forward, reducing the amount of -COOH in the slices. Lower temperatures have the opposite effect.
1.4 Esterification pressure
Higher pressure will push the reaction forward, thus reducing the -COOH content. Lower pressure increases it.
2. Polycondensation reaction
The temperature of the polycondensation reaction also affects the -COOH content. Lowering the temperature can reduce thermal degradation and thus reduce -COOH content. These temperatures are especially those of the final polycondensation tank. However, there are limits to adjusting the temperature. Because lower temperatures also slow down the primary reaction.
The levels in the precondensation and final polycondensation tanks have little effect on -COOH content. Since most esterification occurs in the esterification tank.
3. Production Capacity
When process conditions remain unchanged, reducing production capacity allows longer reaction times. It can lower -COOH content as they continue to react. Increasing production capacity has the opposite effect. So, -COOH content is a key factor in determining the maximum production capacity of polyester equipment.
Conclusion
To ensure high-quality spinning-grade polyester chips, it is essential to control the -COOH content. This can be achieved by:

Cationic Polyester Chips for BCF Yarn
CDP and ECDP Cationic Polyester Chips for Cellulose-Like Fibers
Cationic polyester chips have a special affinity for cationic dyes, making them more easily absorb dyes during the dyeing process, resulting in vibrant colors and high color fastness.
Cationic dyeable polyester chips come in two varieties: CDP and ECDP. CDP fibers are not suitable for blending with other synthetic fibers.
CDP Characteristics:
These are high-pressure cationic dyeable polyester chips, with dyeing conditions set at 120C to 130C and 0.13 MPa.
Advantages of CDP:
CDP fibers exhibit excellent color fastness and vibrant hues.
They facilitate cross-dyeing, resist printing, and variation dyeing effects.
ECDP Characteristics:
ECDP chips vary in Tio2 content, offering both bright and semi-dull options. They can be dyed at standard cationic dyeable polyester chip conditions of 95C to 100C, under room temperature and pressure.
Advantages of ECDP:
With a higher sulfonic acid group content ranging from 2.5% to 7%, ECDP chips boast superior dyeability, allowing for deeper colors.
They also excel in moisture absorption and possess certain anti-pilling properties.
Applications:
These chips are primarily used in the development of cellulose-like fibers.
Through specialized post-spinning false twist processing, they can produce viscose and cotton-like fibers.
They can serve as a partial substitute for nylon 6 fibers.
